You have to turn over a lot of rocks to find those little anomalies. You have to find the companies that are off the map - way off the map. You may find local companies that have nothing wrong with them at all. A company that I found, Western Insurance Securities, was trading for $3/share when it was earning $20/share!! I tried to buy up as much of it as possible. No one will tell you about these businesses. You have to find them.
I don't know that I could draw one that's perfect. But I'd rather by approximately right than precisely wrong, and it would be precisely wrong to turn it down.
We will prosper or suffer in controlled investments in relation to the operating performances of our businesses - we will not attempt to profit by playing various games in the securities markets.
